Racing Genk have announced the sale of Kevin de Bruyne to Chelsea.
The 20-year-old has long been linked with a move to the London giants and saw a deal fail to materialise in the summer.
But Chelsea maintained an interest and have now sealed the move, which will see the youngster stay with Genk on loan until the end of the season.
Genk revealed that De Bruyne put pen-to-paper early on Tuesday morning, signing a contract that commits him to the club until 2017.
Genk have not confirmed the fee, but it is believed that the deal is worth around £7million.
